A 54-year-old man sees spots in his right eye that do not move relative to fixation. He is mildly myopic, and his visual acuity with glasses is 20/20 in each eye. His right eye has multiple small yellowish-white spots in and around the posterior pole, as shown on the color and autofluorescence photographs. His left fundus is normal. Fluorescein angiography shows multiple punctate hyperfluorescent dots associated with spots seen clinically. What is the appropriate management for this patient?
